Dear Doctor: 

Thank you very much for the trust which you have shown by purchasing this autoclave. 

For 55 years now, MELAG — a medium-sized family-owned and -operated company — 
has specialized in the production of sterilization equipment for medical practice. During 
this period, MELAG has succeeded in becoming a leading manufacturer of sterilization 
equipment. More than 400,000 MELAG units sold throughout the world testify to the 
exceptional quality of our sterilizers — which are manufactured exclusively in Germany. 

As all other MELAG products, this autoclave was manufactured and tested according to 
strict quality criteria. Before placing this unit into operation, please read this User Manual 
carefully. The long-term functional effectiveness and the preservation of the value of your 
autoclave will depend on careful preparation of instruments before sterilization, and on 
proper care of the unit. 

The staff and management of MELAG
